IMPROVEMENT lN HORSE HAY-RAKES.

Specification forming partof Letters Patent Nol33,09l, dated November19, 1872.

To all whom it may concern:

Be it known that we, ORRIN L. GENUNG and WILLIAM H. BLACKMAN, of thetown of Caroline, Tompkins county, New York, have invented certainImprovements in Horse-Rakes, of which the following is a specification:

The object of our invention is the dumping of an iron-toothed horse rakeby means of the wheels of the rake, as hereinafter described andclaimed.

We make out of gas or other pipe a revolving axle, to which we attachthree toothed wheels, two next to the wheel-hubs, and one at anyconvenient point on the axle; but preferably at or near the middle ofit. \Ve place the rake-head just so far back of the middle cog-wheel asto clear that wheel, and hinge it fast to the rake-frame. YVe put, atany convenient distance back of the rake-head, a lift ing-bar, whichelevates all the teeth and to it we attach ametallic piece or segment ofa circle, with teeth or cogs, in which plays a toothed click in the endof a lever, operated, preferably, by the foot of the driver, and whichholds the teeth at any convenient distance from the ground; and thiscog-wheel and lever have sei'eral uses. Near the middle cog-wheel, onthe axle of the rake, we put a two-armed lever, whose hub is on theaxle. To one end of this angled lever is fast a click, raised by aspring, and depressed by a handlever. Its object is to catch into-thecog at or near the middle of the revolving axle, and, by the other armof the lever, elevate the teeth of the rake, as it does by being forkedabout the lifting-bar of the rake. A canrsurface is fast near the clickjust spoken of, and out from the click a stud projects *for detachingthis elevating click, so as to clear the cogs of the elevating cog-wheelon the revolving axle, just as soon as the rake-teeth are raised to theproper dumping height.

The following accompanying figures are designed to show the parts justnamed, as well as other parts connected with them, viz: Figure 1, apartial side elevation, showing the mechanism of our rake 5 Fig. 2, aview of the frame and arrangement of our rake, as seen by inverting ourrake, or placing it bottom side upward; Fig. 3 shows the elevating-leverand its click; and Fig. 4, the angled lever, which throws the click ofthe elevating-lever in gear with the cog-wheel at or near the middle ofthe axle.

In Fig. 1, a is one of the wheels that support the rake; and IN), theframe and thills of the rake fast to the revolving axle c; and dis theelevating cog-wheel, fast to the revolving axle at or near its middleand e is the rake-head, hinged to the frame b; and) the elevating-barfor the rake-teeth; and g is the two-armed lever, journaled loosely onthe axle; and h is its elevating-click, thrown, by by the hand-lever i,at the pleasure of the operator, in gear with the cog cl. At j is seenthe segmental cog, fast to the. elevating-bar; and at its upper end thetooth of the footlever 7c is in gear with the segment j and at lis thecam-surface for the stud m, projecting from the click h to slide on, andthus throw the click h out of gear from the wheel (I. r

The operation of these just-named parts is, that the driver, seated at1', lets the rake run until the cavity 0 of .the' rake-teeth is filled,when he, by the hand-lever i, depresses the click It into theconstantly-turning cog d, when this cog, by the click h, pushes thetwo-armed lever 9 forward, and thus the elevating-bar f is raised, andthe rake-teeth with it, until the stud 1);, bearing on the cam-surface 1disengages the click h from the teeth of the cog d, and thus the hay'isdumped; and in the meantime the segment j has run up by the tooth on theend of the foot-lever k, and thus the teeth of the rake are held fromtheground until the driver puts his foot on the lever k, when therake-teeth fall, and raking agai'n commences. By the repetition of thisoperat-ion, with these simple devices, the rake is used as long as theoperator desires.

In Fig. 2 the same letters show the same parts.

At n and n on the axle c is seen two cogwheels fast to the axle, withtwo clicks' fast to the wheels, to and a. The action of these cogs andclicks is to let either wheel revolve in turnin g the rake, while theaxle revolves continually whenever the rake advances.

The advantages and uses of Our invention are considered as apparent tothose skilled in the art to which it appertains.

Claims.

1. The toothed segment j, and bar f, in combination with the foot-leverk, substantially as and for the purpose described.

2. Thecombination of axle c, cog-wheels on the axle, armed lever g,click h, and cam 1, combined with the bar f, segment 7', and lever 70,

substantially as and for the purpose described.

3. The combination, of the hand-lever i constructed as described, theclick h, wheel d, the two-armed lever g, with the bar f, segment j, andfoot-lever 70, substantially as set forth.
